    • An elastic body 51 is provided to absorb impact energy generated by the collision between rotor positioning portions 31 and shaft portion positioning portions 29 when a shaft portion 24 is moved into a female thread portion 26 to determine the initial position of the shaft portion 24, and so the impact noise generated by the collision between the rotor positioning portions 31 and the shaft portion positioning portions 29 can be reduced. Also, the force of impact imparted to the shaft portion positioning portions 29 by the rotor positioning portions 31 decreases, and so it is possible to prevent deformation of the rotor positioning portions 31 and the shaft portion positioning portions 29.
    • 提供弹性体51,以便当轴部分24移动到内螺纹部分26中以确定轴部分24的初始位置时,吸收由转子定位部分31和轴部定位部分29之间的碰撞产生的冲击能量,并且 因此可以减少由转子定位部31与轴部定位部29之间的碰撞产生的冲击噪音。 此外,由转子定位部31向轴部定位部29施加的冲击力减小,因此能够防止转子定位部31和轴部定位部29发生变形。
